Question

In a parallelogram ABCD the diagonal bisect each other at O.angle abc=30degree,angle BDC=10degree and angle cab=70degree.find.
angle DAB, ANGLE ADC,angle BCD, angle AOD,angle DOC, ANGLEBOC, angle AOB, angle ACD, angle ADB, angle ACB, angle DBC and angle DAB?​

Answer 1

Step-by-step explanation:

ACD=BAC=70°,

ABC=ADC

30°=10°+BDA

BDA=20°,

ADC=20°+10°=30°,

ADC+DAB=180°

30°+70°+DAC=180°

DAC=80°,

DAC=ACB=80°
